Description

Ultrasonic humidifier {ULTRASONIC HUMIDIFIER}

The present invention relates to an ultrasonic humidifier.

A humidifier is one that generates water vapor for indoor humidification, and may be classified into a heating type, a vaporization type, and an ultrasonic type according to a steam generation method. In a heating humidifier, water is directly heated to generate steam, in an evaporative humidifier, water vapor is generated by contact between water and air, and in an ultrasonic humidifier, water is molecularized by ultrasonic waves to generate steam.

In particular, in the case of ultrasonic humidifiers, product prices and operating costs are inexpensive, so they are mainly used. However, in the case of such an ultrasonic humidifier, foreign substances such as various organic or inorganic substances contained in water are discharged into the room together with water vapor, or various contamination by foreign substances remaining after steam is generated is a problem. In the case of using purified water to solve this problem, contamination due to the propagation of various microorganisms including bacteria may be concerned.

Hereinafter, an ultrasonic humidifier according to a second embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a schematic configuration diagram of an ultrasonic humidifier according to a second embodiment of the present invention. Among the components of this embodiment, the same components as those of the above-described first embodiment of the present invention are referenced by reference numerals in FIG. 1, and detailed descriptions thereof are omitted.

Referring to FIG. 2 , in this embodiment, the distillation unit 302 includes first to third thermoelectric elements 320, 330, and 340. The first to third thermoelectric elements 320, 330, and 340 generate heat and absorb heat at different temperatures, respectively. Substantially, the first thermoelectric element 320 generates heat at a relatively low temperature and absorbs heat at a relatively high temperature compared to the second thermoelectric element 330 . The second thermoelectric element 330 generates heat at a relatively low temperature and absorbs heat at a relatively high temperature compared to the third thermoelectric element 340 .

More specifically, the first thermoelectric element 320 includes a first heating surface 321 generating heat at a first heating temperature and a first heat absorbing surface 322 absorbing heat at a first endothermic temperature. The second thermoelectric element 330 includes a second heating surface 331 generating heat at a second heating temperature and a second heat absorbing surface 332 absorbing heat at a second endothermic temperature, and the third thermoelectric element ( 340) includes a third heat generating surface 341 generating heat at a third heat generating temperature and a third heat absorbing surface 342 absorbing heat at a third endothermic temperature. At this time, the second heating temperature is set to a temperature relatively higher than the first heating temperature, and the third heating temperature is set to a temperature relatively higher than the second heating temperature. In addition, the second endothermic temperature is set to a temperature relatively lower than the first endothermic temperature, and the third endothermic temperature is set to a temperature relatively lower than the second endothermic temperature.

In addition, the first to third heat generating surfaces 321, 331, and 341 are disposed from upstream to downstream in a direction in which water flows through the heating pipe 221, and the first to third heat absorbing surfaces ( 322, 332, and 342 are disposed from upstream to downstream in a direction in which water vapor flows through the heating pipe 221. Therefore, in this embodiment, the water flowing through the heating pipe 221 is gradually heated to a high temperature by the first to third thermoelectric elements 320, 330, and 340 and vaporized into water vapor, and the cooling pipe Water vapor flowing through 222 is gradually cooled to a low temperature by the first to third thermoelectric elements 320, 330, and 340, and is liquefied into distilled water.

Meanwhile, in the present embodiment, in the heating pipe 221, water flows from the bottom to the top while being heated by the first to third thermoelectric elements 320, 330, and 340 and vaporized into water vapor. In the cooling pipe 212, water vapor flows from top to bottom and then flows from bottom to top, being cooled by the first to third thermoelectric elements 320, 330, and 340 to be liquefied into distilled water. . To this end, the heating pipe 221 may be formed in a straight line shape, and the cooling pipe 222 may be formed in a U shape with one end connected to the heating pipe 221 . In addition, one end of the connection pipe 223 may be connected to the lower end of the cooling pipe 222 . However, in this embodiment, the connection pipe 223 connects the cooling pipe 222 and the distilled water tank 400 without passing through the heating pipe 221 .

In addition, this embodiment further includes an exhaust port 222H and a valve unit 700. The exhaust port 222H and the valve unit 700 are where water vapor flowing inside the cooling pipe 222 is discharged to the outside of the cooling pipe 222 .

More specifically, the exhaust port 222H is formed on one side of the cooling pipe 212 . For example, the exhaust port 222H may be formed at a front end of a portion of the cooling pipe 222 extending in a horizontal direction. Substantially, the exhaust port 222H is a place where water vapor flowing inside the cooling pipe 222 is discharged to the outside of the cooling pipe 222 .

In this embodiment, the exhaust port 222H is located at one side of the cooling pipe 222 corresponding to a relatively downstream side in the direction in which water vapor flows through the cooling pipe 222 compared to the third thermoelectric element 340. is formed This is to ensure that water vapor flowing through the cooling pipe 222 is preferentially cooled by the first to third thermoelectric elements 320, 330, and 340 to be liquefied into distilled water. In other words, rather than directly discharging the water vapor heated and vaporized by the first to third thermoelectric elements 320, 330, and 340 into the room, it is liquefied with distilled water and then used by the ultrasonic generator 500. It is more efficient to miniaturize and discharge indoors. Therefore, in the present embodiment, the water vapor flowing through the cooling pipe 222 is not discharged into the room through the exhaust port 222H, but preferentially to the first to third thermoelectric elements 320, 330, and 340. The position of the exhaust port 222H is limited so that it is cooled and liquefied by water vapor.

And the valve unit 700 selectively opens and closes the exhaust port 222H. In particular, the valve unit 700 opens the exhaust port 222H when the internal pressure of the cooling pipe 222 exceeds a predetermined reference pressure.

In this embodiment, the valve unit 700 includes a valve body 710 and an elastic member 720. The valve body 710 is movably installed in the cooling pipe 212 to selectively open and close the exhaust port 222H. For example, the valve body 710 is installed in the cooling pipe 222 so as to be movable left and right in the drawing, and the exhaust port 222H opens in a state in which the valve body 710 is moved to the right in the drawing. It may be shielded by the valve body 710 . The elastic member 720 applies elastic force to the valve body 710 so that the valve body 710 blocks the exhaust port 222H. That is, the elastic member 720 applies elastic force to the valve body 710 to move the valve body 710 to the left in the drawing. And, when the internal pressure of the cooling pipe 222 exceeds the reference pressure, the valve body 710 moves to the right in the drawing with respect to the cooling pipe 212 while overcoming the elastic force of the elastic member 720. to open the exhaust port 222H.

Therefore, according to the present embodiment, when a large amount of water vapor is required for indoor humidification, the water flowing through the heating pipe 221 is heated to gradually increase in temperature, and the water flowing through the cooling pipe 222 The water vapor is cooled so that the temperature gradually decreases. Therefore, according to this embodiment, distilled water can be produced more efficiently and indoor humidification using the distilled water can be achieved.

Also, in this embodiment, when the internal pressure of the cooling pipe 222 is excessive, water vapor flowing through the cooling pipe 222 is discharged into the room through the exhaust port 222H. Therefore, according to this embodiment, while maintaining the internal pressure of the cooling pipe 222 within a safe range, indoor humidification can be achieved.

Within the scope of the basic technical idea of the present invention, many other modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the appended claims. will be.
